I use Community Server API and having problems with sharing an event in a calendar with another user. I can create/update an event but I can't share it while creating/updating. According to the documentation I should send a list of sharing options in the header with a parameter called "sharingOptions". I've tried many things but haven't been able to figure out what kind of an object the sharingOptions list's objects should be. Does any of you have an idea what to do? Here is the corresponding documentation link:
